Answer 1

Eli Assouline

#6#

#x-7=5-x# Add #x# on both sides and add #7# on both sides

#2x=12#

Dividing both sides by #2#

#x=6#

To solve the equation (x - 7 = 5 - x), first, add (x) to both sides of the equation to get (2x - 7 = 5). Then, add 7 to both sides to isolate (2x) and get (2x = 12). Finally, divide both sides by 2 to solve for (x), giving (x = 6).
